Add the butter and oil to the Instant Pot. Hit “Sauté” and “Adjust” so it’s on the “More” or “High” setting and wait until the butter has melted and it bubbles.

Add the onion and cook for about 2 minutes so it softens and just lightly browns. Add in the butternut squash and stir with the onions for another 1-2 minutes (the squash will be very hard, but don’t worry – it will completely soften up after pressure cooking). Next, add in the mushrooms, stir and cook for another minute. Finally, add the garlic, stir with everything else and cook for another 3 minutes.

Add in the white wine and once it bubbles, let it do so for another 2 minutes so some of the alcohol burns off. Add rice and stir. Add in the broth, seasoned salt, white pepper, black pepper, nutmeg, Italian seasoning and dried parsley. Stir well, deglazing the bottom of the pot and then place the spinach on top (but do NOT mix in with everything else – just let it rest on top. Also, it may look like a LOT of spinach is in there but you’ll be shocked at how it cooks down).

Secure the lid, hit “Manual” or “Pressure Cook” High Pressure for 6 minutes. Quick release when done and stir the spinach in with the risotto (when you do this, the spinach will have become nothing but little green strands).
